Here's Dwyane Wade talking about the one BIG hangup he had when it came to stripping down naked for ESPN ... and it ain't something you'd expect from the guy.
D-Wade was at LAX when we brought up the spread from ESPN The Magazine's Body Issue ... a spread his famous wife Gabrielle Union LOOOVEEED!!!
Check out his face when we read some of her tweets ... including the one where she wrote, "Why dontcha circle back to the house... meet ya in 10."
Wade blushes ... it's adorable.
BONUS -- We also asked about the chances he teams up with LeBron sometime again in his NBA career.
